UPDATE @ 4:58 p.m.:
According to a statement from the Butler County Sheriff's Department, the 14 year-old suspect, now in custody, entered the school's cafeteria at lunchtime armed with a handgun and shot two students before fleeing the school. Two other students were injured but not from gun shots.
"We do not have a motive at this time," said Sheriff Richard K. Jones in the statement. "But we do know all the kids involved are students of Madison High School."
13-year-old Shelby Kinnin was in the cafeteria when shots rang out.
"You just here these couple like bang bang bang really loud," she said. "At first I thought it was a chip bag or something but then I was like that's too loud and there's too many of them."
"It's unnerving seeing a SWAT team at your kid's school. There's no feeling like that in the world," said Stephanie Kinnin, Shelby Kinnin's stepmother.
Butler County Sheriff Richard Jones says the shooter is being charged with attempted murder, felonious assault, inducing panic and making terroristic threats. He is currently in juvenile jail.
